Patent DE-4031978-A1 (DE)
Inventor: HAHN ULRICH
IPC: C02F11/12
Filed: 1990-10-09
Abstract: A waste disposal device is described for aqueous waste materials, such as sewage sludge, wet waste from gardens or the like, in which the evaporation energy necessary for drying is obtained, at least to a considerable extent, from burning the solid content of the starting material. The device consists of a mechanical predryer (3), fluidised-bed dryer (4), solid separator (12), solid burner (6), ash separator (5) and heat exchanger (7). The fluidised-bed drying and the solid burning with the associated separators and blowers (8, 9) and distributing devices are combined into a compact unit, accommodated on an engine-driven vehicle. The mechanical predrying is arranged separately from this on a towable trailer (2). <IMAGE>
Patent DE-4032617-A1 (DE)
Title: Automatic cops change
Inventor: HAASEN ROLF
IPC: B65H69/00
Filed: 1990-10-15
Abstract: The automatic yarn repair and cops change system, at a winder, has a yarn cleaner (27) in the yarn path to register the presence, movement and dimensions of the yarn (35). The swing paths of the carrier (24) for the yarn from the supply bobbin (4) and the suction jet (34) for the yarn of the winding bobbin (38) each overlap with the yarn cleaner. The position of the carrier is shown by a signal to be coupled in a logic circuit with the signal showing the presence of a yarn from the supply bobbin at the yarn cleaner. After a feed movement of the carrier, should the signal show that no yarn from the supply bobbin is present, a control circuit triggers the cops change mechanism (6,13,17,19). After the cops has been exchanged, the carrier repeats the sequence to grasp a yarn and take it to the bonding point.  Pref. the control system imposes a time displacement on the movements of the carrier for the yarn from the supply bobbin and the suction jet from the yarn from the winding bobbin, so that the active search for the yarn from the winding bobbin is after the check on the supply yarn. The control stops the yarn bonding unit drive if no supply yarn is present at the carrier after its movement, and before the cops change mechanism (6,13,17,19) is activated, and the carrier is returned to its start position and normal drive. A counter records the number of failed yarn searches to trip the cops change action after a given number of attempts. A blower system (14,15,16) at the supply bobbin (4) directs an air stream from the bobbin towards the yarn catch position (25) of the carrier (24).

Title: Security store for keys - opens individual doors under own wt. following coded release
Inventor: STAREC ROLF DIPL ING
IPC: G07C9/00
Filed: 1991-01-17
Abstract: The separate keys (3) are deposited into separate trays (2) and swung into a self-locking position. A ratchet catch (7) grips a cam (5) on the tray and locks the position.

Title: Predictive controller initiation process - not requiring complete dynamic mathematical model
Inventor: DAMERT KLAUS DR
IPC: G05B13/02
Filed: 1991-03-22
Abstract: In a process for setting the parameters of and initiating operation of a predictive controller for monotonously varying single or multiple variables by calculating the trend of the control variables without use of a model, the novelty is that (i) the time horizon (t) of the controller is set at a third of the time needed to complete a target value change of the variable to be controlled; (ii) the controller cycle time (delta t) is set at one-tenth of the time horizon for stable variables and at a small value for instable variables so that smooth adjustment is obtained; and (iii) starting from the stationary state, the control value changes are determined from the unitary adjustment value changes remaining after time t and the controller is initially operated using these data and a smoothing parameter alpha of 0.9, which is increased to eliminate any obtrusive h.f. fluctuations superimposed on the control value curve, and is subsequently operated using any desired controller cycle times (delta t) with a smoothing parameter of alpha exp (t/delta t). USE/ADVANTAGE - The process is useful for predictive control of a distillation column. It avoids the need for a complete dynamic model of the process to be controlled and requires very little experimental information.

Title: Stirring infusion process for home coffee percolator - uses the gravitation filter principle and a dynamic infusion into a spinning filter below a stirring infusion jet operated by a small gear
IPC: A47J31/06
Filed: 1991-07-08
Abstract: Through the movement produced by the infusion element, filter (2) and/or jet (3), the infusion surface (1) is squirted as uniformly as possible over all the areas. Even the coffee powder deposited at the filter periphery is frequently reached by the scalding process. To reach an infusion surface as large as possible the stirring frequencies of the filter element and the jet are different. The proportion between the stirring jet frequency and the filter rotation frequency is uneven and greater than 5:1. No centrifugal power is exercised on the coffee powder. The infusion process is optimised through a dynamic infusion combined with a time intensify scald. A small battery operated gear added to the water holder or developed inside the coffee percolator itself achieves the filter spinning and/or jet stirring. A switch (19) allows selection between speed quality factor. ADVANTAGE - Guarantees advantages development of coffee aroma and economises coffee powder.
